Guy with problem in system-ui, try this:

For Open mode users:
1. T-3-1-4-1 -> wait until it will finish process
2. T-3-1-3-1 (or what you want, like 2 3 4 5) -> wait until it will finish process
3. If you want menu with notification: T-3-2-2

For Inception users:
1. T-3-1-2-1 -> wait until it will finish process
2. T-3-1-1-1 (or what you want, like 2 3 4 5) -> wait until it will finish process
3. If you want menu with notification: T-3-2-2

If still have problem try to reboot...
